Instead of guest Comedy Controllers, choosing their comedy favourites, it is now the turn of those who, in their own ways, have to take the blame for many of the shows often featured on Radio 4 Extra.

In front of an audience in the iconic Radio Theatre in Broadcasting House - the home of British Radio comedy - they reveal why they do it and what it was (and is) that made them laugh.
